rule of thumb - if its computer to computer - nothing else in between you will need a cross over cable, if its a router, wall socket, patch panel then it will always be a straight through or patch cable as we call hem over here

only different between the two is that on one end two of the wires need to be crimped onto different pins - think its 4 and 6 not too sure been such a long time since i had to do any

Thanks guys all went well, after I made a fool out of my self because I did not know that the ends had to be crimped before you put them in the jack. I was hoping to try them out before I crimped them.
